This dataset is the GEOS-Chem model output used in the following publication, Jacobs, N., Simpson, W. R., Graham, K. A., Holmes, C., Hase, F., Blumenstock, T., Tu, Q., Frey, M., Dubey, M. K., Parker, H. A., Wunch, D., Kivi, R., Heikkinen, P., Notholt, J., Petri, C., and Warneke, T.: Spatial distributions of XCO2 seasonal cycle amplitude and phase over northern high latitude regions, Atmos. Chem. Phys. Discuss. [preprint], https://doi.org/10.5194/acp-2021-185, in review, 2021. The version 2 zip file contains three directories. CO2_tracers_daily/GEOSChem.taggedCO2.YYYYMMDD.nc files: this directory contains the CO2 simulation as defined by Jacobs et al. (2021). YYYY indicates year, MM indicates month, and DD indicates day. CO2_tracers_monthly/GEOSChem.taggedCO2.YYYYMM.nc files: this directory contains the CO2 simulation as defined by Jacobs et al. (2021). YYYY indicates year and MM indicates month. TT_tracers/GEOSChem.TTtagged.YYYYMM.nc files: this directory contains the tagged tracers simulation as defined by Jacobs et al. (2021). YYYY indicates year and MM indicates month. The version 1 zip file contains only the monthly mean directories.
